FLEX STACK
Robotic gantry palletizer and depalletizer | automated case palletizing | beverage food and CPG packaging lines
Manual palletizing is one of the most injury-prone jobs on a production floor. CODI's Flex Stack is a compact gantry palletizer and depalletizer built for facilities where floor space is limited and labor is at a premium. Unlike collaborative robots (cobots) with limited payload capacities, Flex Stack handles up to 110 lbs per pick, making it capable of stacking heavier cases that cobots simply can't manage. It runs 4 to 15 cases per minute depending on configuration, supports single, dual, or triple bay pallet stations, and uses a browser-based interface that lets your team adjust patterns and case dimensions without outside programming support. Simple linear gantry mechanics mean fewer wear points and more predictable maintenance than multi-axis robots. It works across food and beverage, co-packing, CPG, and industrial applications, and for most operations labor savings alone bring ROI within the first year.

Predictive Analytics
Manual palletizing is hard manual work. The Flex Stack Pro automates it with a compact gantry design that fits tight spaces, handles up to 110 lbs per pick, and runs up to 15 cases per minute. No coding required. Your team programs patterns through a standard web browser.
PRODUCT FEATURES
Higher Payload Than Cobots
At up to 110 lbs per pick, the Flex Stack Pro handles loads that collaborative robots can't. Heavier cases, faster builds, more stable stacks.
Browser-Based Pattern Programming
No external programmer needed. Your team adjusts case dimensions, stack patterns, and pallet configurations through any standard web browser, with automatic pattern generation and 3D visualization built in.
Simple Gantry Mechanics
Cartesian linear axes have fewer wear points than multi-axis robots. That means more reliable uptime and maintenance your own team can actually manage.
Dual-Pallet Continuous Operation
A dual-pallet configuration keeps the system running while one pallet is swapped out. No stopping the line to reload.
